在估算一批塑料件注塑加工成本的时候，除了要将加工费、材料费、包装费等都考虑在内之外，还要结合原料的损坏率进行计算。因为材料和产品的损坏会影响注塑加工成本的高低，到底有多大的影响呢？下面济南注塑加工厂家为您讲解下。

When estimating the injection molding processing cost of a batch of plastic parts, in addition to taking into account the processing cost, material cost, packaging cost, etc., it should also be calculated in combination with the damage rate of raw materials. Because the damage of materials and products will affect the cost of injection molding, how much impact? Next, Jinan injection molding manufacturer will explain to you.

先要知道哪些原因会造成注塑加工件的损坏，比较常见的有更换塑料模具时的洗模用料；热度不够造成的废品；生产过程中产生的水口等等，这些都属于损坏。

First of all, we should know what causes the damage of injection molding parts. The more common ones are the mold washing materials when replacing plastic molds; Waste products caused by insufficient heat; The nozzle produced in the production process is damaged.

也就是说，如果将一吨材料投入加工，结果生产出了0.7~0.8吨的产品，我们就会认为损耗率是20%~30%左右。

In other words, if one ton of material is put into processing, and 0.7~0.8 tons of products are produced, we will think that the loss rate is about 20% - 30%.

这样的话，在计算成本的时候也要将这百分之二、三十的损坏率加进去，这样得到的数据才会比较准确。事实上，这样的损耗率还是比较正常的，而且如果要节约加工成本的话，也可以从降低材料损耗率着手。

In this case, the damage rate of 2% or 30% should also be added when calculating the cost, so that the data will be more accurate. In fact, such a loss rate is relatively normal, and if you want to save processing costs, you can also start from reducing the material loss rate.

根据经验进行估算模具的公式：

Formula for estimating mold price based on experience:

注塑模具=材料费+设计费+加工费和利润+增值税+模具试模费+包装运输费

Injection mold price = material fee + design fee + processing fee and profit + VAT + mold trial fee + packaging and transportation fee

比率通常为：

The ratio is usually:

材料费：材料和标准件占注塑模具总成本的15％-30％

Material cost: materials and standard parts account for 15% - 30% of the total cost of injection mold

手续费及利润：30％-50％

Handling charges and profits: 30% - 50%

设计费：注塑模具总费用的10％-15％

Design fee: 10% - 15% of the total cost of injection mold

模具试模费：大中型模具可控制在3％之内，小型精密模具可控制在5％之内

Mold trial fee: large and medium-sized molds can be controlled within 3%, and small precision molds can be controlled within 5%

包装运输费：可按实际计算或3％计算

Packaging and transportation cost: it can be calculated according to the actual situation or 3%

增值税：13％

VAT: 13%
